The Maugean skate, a stingray-like animal, is on the brink of extinction. It is found only in Macquarie Harbour on Tasmania’s west coast, part of which lies within the Tasmanian Wilderness World Hertage Area. Australian Government Conservation Advice clearly identifies fish farming, which has depleted oxygen levels in Macquarie Harbour, as having the most detrimental impact on the threatened skate.
Meanwhile, the industry, with government funding assistance, is undertaking a trial of dubious merit to re-oxygenate Macquarie Harbour, as if it is just a large aquarium, in a desperate bid to avoid having to do the obvious and de-stock the salmon farms.
It our recent submission to the federal EPBC review of salmon farming in Macquarie Harbour, the TNPA urged Environment Minister Plibersek to revoke the 2012 NCA-PM decision which allowed the expansion of marine farming in Macquarie Harbour. It should be replaced with a decision to prohibit salmonid aquaculture in those waters.
